Abstract: An aspect of the present invention includes a protocol for conveying data during an e-commerce session with a polymorphic response, comprising initiating a session with a message from a buyer application to a broker application and a session identifier assigned by the broker application; conducting the session between the buyer application and a supplier application; and concluding the session with a additional message which includes a schema identifier for the additional message, resolvable in a context of a system identifier, and a polymorphic response comprising a type and a version, wherein the polymorphic response includes additional data elements corresponding to values assigned to the type and version.

Abstract: A system for logically segmenting document elements from a document includes an input port for inputting a signal representing the document image, a computer having a document structural model, a document white region extraction system that extracts major white regions separating document elements in the input document image, and a string translation device that generates matching one-dimensional data string that corresponds to the extracted major white regions in a document image, a comparison device that selects the optimum path through a finite state machine representing acceptable column layouts for the source document, and a columnar layout identification device that identifies the column layout defined by the optimum path. Then, the identified column of document elements may be processed to logically tag or extract document elements.
